Topologies for External User Access

 

Topic Last Modified: 2011-02-03

Providing external user access for Microsoft Lync Server 2010 communications software requires that you deploy at least one Edge Server and one reverse proxy in your perimeter network. Additionally, you may need to deploy a Director in your internal network.

If you need greater capability than a single Edge Server can provide, or if you need high availability for your edge deployment, you can deploy multiple Edge Servers and configure load balancing. If your organization has multiple data centers, you can have Edge deployments at more than one location. However, only one of the Edge deployments can be designated as the federation route.

This section describes the reference topologies for edge deployments. For details about the components that make up the topology, see Components Required for External User Access in the Planning documentation.

All edge services run on each Edge Server. Services cannot be split between two different Edge Servers. If you deploy an Edge Server pool for scalability, all edge services are deployed on each Edge Server in the pool.
